2. A letter of Bishop Ivo of Chartres (Ep. ccxi., Migne, _Patrologia_, vol. 162, cols. 215, 216), written about A.D. 1110, makes Constance’s mother sister, not of Fulk, but of his father Geoffrey Greygown. So does an anonymous chronicle ending in 1109, printed in Duchesne’s _Hist. Franc. Scriptt._, vol. iv. p. 96. 3. The Chron. S. Albin. (Marchegay, _Eglises_, p. 21) has under date 987: “Hlotharius rex obiit.... In isto reges Francorum defecerunt. Hic accepit uxorem Blanchiam filiam Fulconis Boni comitis Andegavensium, patris Gaufredi Grisegonellæ, et habuit ex eâ filiam, Constantiam nomine, quæ fuit data cum regno Roberti regis filio, scilicet Hugonis Magni.” Wildly confused as this passage is, I believe that it really contains a clue to the identity of Constance’s mother. Whoever she was, she certainly must, at the time of Constance’s birth, have been wife not of Louis the Lazy (who is evidently meant, instead of Lothar), but of Count William I. of Arles. Now it is plain (see Vic and Vaissète as above, pp. 62, 63) that William was twice married; first to Arsindis, who was living 968–979; and secondly, to Adelaide, who appears in 986, was mother of his successor William II., and apparently still living in 1026. Of Arsindis nothing further is known; but with Adelaide the case is otherwise. King Louis the Lazy, at some time between 978 and 981, married a lady “ab Aquitanis partibus” (R. Glaber, l. i. c. 3, _Rer. Gall. Scriptt._, vol. x. p. 5), whose name was Adelaide according to Richer (l. iii. c. 92), but whom the Chron. S. Albin. (as we have already seen) and the Chron. S. Maxent. (a. 986, Marchegay, _Eglises_, p. 382) call _Blanche_. After two years of marriage with the young king she divorced him, or was divorced by him, and married _William of Arles_ (Richer, l. iii. cc. 94, 95). This is clearly the lady of whom we are in search. The dates fit exactly; William’s first wife, Arsindis, is dead; he marries the divorced queen, probably about 982–983, and they have a daughter who in 1000 will be, as Constance evidently was at her marriage, in the prime of girlish beauty. The probability is strengthened by the fact that Adelaide’s first husband actually was what R. Glaber (l. iii. c. 2, _Rer. Gall. Scriptt._, vol. x. p. 27) mistakenly calls Constance’s father, count of the “First Aquitaine,” or Toulouse; for Richer (l. iii. c. 92) says she was widow of Raymond “duke of the Goths,” _i.e._ of Septimania or Toulouse:--by the name of “Candida,” the Latin equivalent for “Blanche,” given to the wife of William of Arles by Peter of Maillezais (l. i. c. 6, _Rer. Gall. Scriptt._, vol. x. p. 182; see above, p. 173, note 5{386});--and even by the blundering Angevin chronicle which makes Constance a daughter of “Blanche” and “Lothar,” meaning of course Blanche the wife of Lothar’s son, and her third husband. This same Chron. S. Albin., however, adds that the said “Blanche” was a daughter of Fulk the Good.
